Should we set a lower constraint on the python version?

Currently, RuleTree supports only Python 3.12. This is due to the introduction of the hyperparameter delete_on_close in the base Python package tempfile (more here).

This package is essential for creating the (beautiful) plots for shapelet-based decision trees since we need to save somewhere all the shapelets images before rendering the final plot.
This strictly relates to #15, since changing the tree visualization module may not require saving intermediate images.

Maybe a fix could be this (if it works)

Would support 3.10 and up, and use dependencies groups instead. Maybe suggest installing w/ 3.12 for using plotting
